Serial No. 61 1,943.

This invention relates to new and useful improvements in a parachute.

The invention has for an object the construction ofa parachute which is character ized by a sail carrying a plurality of tunnelshaped members upon its edge arranged for directing air within the sail to inflate it.

Another object of this invention is the provision of a cup-shaped container for attachment upon the back of a person and provided at its top edge with a plurality of rings capable of co-acting with said funnel-shaped members to insure the proper directing of air within the sail.-

As another of the objects of this invention, it is proposed to provide resilient means for connecting each of the funnel members with each of the rings.

Furthermore, as another object of this in- 26 vention it is proposed to arrange a drum rotatively upon the bottom of said'cup-shape'dcontainer and connected with ropes with the sail for the purpose of drawing the sail. into its inoperative position. As another object of this invention it i proposed to arrange rings upon the bottom of each of the funnels and to connect the cableswhich connect With the parachute sail with said rings.

39 Furthermore, as another object of this invention it is proposed to construct a device of the class mentioned which is of simple, durable construction, dependable in use and eflicient inaction, and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure Fig. 1 is an elevational view of the parachute in use. 3

Fig. 2 is an enlarged fragmentary sectional view through one of the funnels on the edge I of the parachute sail andlooking towards the Fig. 3 is a fragm'entaryhoriz ontal sectional view taken on the line 3 -301 Fig. 21 p V Flg. 4 is a perspective view of the container for attachment upon ones back to which the j I sectional View sail is connected by cables. Fig. 5 is a fragmentary showing one of the funnels from the parathe container. i g

Fig. 6 is" a fragmentary horizontal sec tional view taken on the line 6'6 of Fig. 5; The parachute, according to this invention,- comprises-a-sail 10 of customary shape and construction. A plurality offunn'el-shap'ed members 11 are attached at spaced distances along the pe'riphery' of the sail 10. The at tachment isaccomplished by bosses 12' from" chute sail engaging one of the rings from the funnel-shaped member"beingj formed with apertures through whichfbolts-1'3 pass. Washers 14: are located upon thefouter' face of the parachutesail so astoii'nsure proper connection of the parts. Ondiametrically opposite sides on the bottom of the funnel rings 15 are attached throughwhicha con- .tinuous rope 16 passes which connects With a cable l7 extendin *downwardsfto'jthe' containerportion of t e parachute as hereinafter fully described. r s v f The container portion comprises acupshaped container 18 for attachment upon ones back'. For this purpose, upon one side bosses 19 protrude and su ort-strapsm capable of engaging over onesjshoulder and.

across the'chest to accomplish the attachment. Bottom apertures 21are formed with in the bottom of the cup-shaped container 18 tor the purpose of allowing air to enter. A plurality of rings 22 are attached along the periphery of the cup 18 along diameters to project from the cup and-correspond in numberiwiththe funnel-shaped'members 11. These rin s are adapted to support the funnel-shape 'members when the" parachute is in a collapsed position.

Each of the rings 22 projectto the outside and to the inside of the container so that air from the outside and inside may enter the tunnels. At diametrically opposite sides the ring 22 is formed with cutout portions 24 through Which resilient springs 25 project;

' holding the parts thus connected.

' bottom of the container.

the purpose of turning the drum to draw the descending with the parachute.

These springs are engageable against peripheral grooves 26 formed within a shoulder portion 27 upon the bottom of the funnel 11. This shoulder portion allows the funnel to properly, seat on the top ring while the springs 25 engage the grooves 26 resiliently The ropes 17 extend selectively through the rings 22 and then through an openlng 28 in the bottom of the container 18. From there they extend about a drum 29 rotative- 1y supported on lugs 30 projecting from the ropes thereon. In Fig. 1 a man 32 is shown Normally, the parachute sailis disposed withinthe cup-shaped-contained 18 and each ofthe funnel members 11 are engaged selec tively upon the rings;22.' When the parachute is used it is first strapped uponones back. Then when the person jumps out from the plane into space air will enter the openings 21 and pass through the rings 22 and join with otherfairpassing through the rings from the outside of the container, and then through the funnels 11 into the parachute sail. The arrangement of the-rings of the funnel insure the opening of the sail. As soon as stress takes place betweenthe sail 10 which is opening and the container 18, the funnel members 11 will be snapped out from engagement with therings 22 in that the springs 25 will give to allow disengagement of the parts. Then the parachute sa1l assumes an open position way up above the container as shown vin Fig. 1., and the person may land safely, V i 1 While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new, and desire to secure by United States Letters Patent is 1.
